Contribution of the Bc Institute - Zagreb to the breeding and seed produstion of winter wheat in the Republic of Croatia

The breeding of winter wheat in the Bc Institute for breeding and production of field crops - Zagreb was initiated in 1947 by dr. Potočanac. After many investigations Italian wheat cultivars were introduced into production in Croatia after 1956. Because of several crucial failures, the most important cause of which was insufficient winter hardiness, he established a new wheat cultivar model combining the good traits of Italian and American cultivars. From this concept to famous wheat cultivars were released Zlatna dolina and Sanja. The cultivar Zlatna dolina gave 15 percent higher yields in general production then the leading Italian cultivar Libellula (Martinić-Jerčić, 1990). The stability of this high yield potencial was expanded as the next step in breeding wheat for resistance to the most important fungal diseases: powdery mildew, stem rust, Septoria spp. and Fusarium spp. This wheat cultivar model was followed whit certain changes and improvements, by the breders who continued this work: P. Javor, S. Tomasović and R. Mlinar. It is evident that this orientation in breeding was correct, because 56 cultivars were released, 9 of which were registered in foreign countries (Hungary, Italy, Czechoslovakia, Bulgaria and Slovenia).
